Roddick had his calf muscles massaged in the third set, saying they were cramping, before resuming the match. Lapentti said he thought Roddick was exaggerating.

"Everyone has a different point of view and I think tennis is a sport where you have to be gentlemanly," said Lapentti, who was in Roddick's face arguing for several minutes after the match. "It's not the first time he's done this."

- Lindsay Davenport, in her second WTA tournament since undergoing surgery on her right knee in January, needed just over an hour to defeat Marie-Gaianeh Mikaelian 6-3, 6-0 in the second round of the Acura Classic at Carlsbad, Calif.

"I'm really happy where I am at," Davenport said. "It really is above what I expected."
